I like this, though it comes off just a tad oversaturated and cartoonish on my screen. Of course, I don't know if that's what you were really going for or not. Consider that a personal preference thing on my part.
Is that a typo in your title or are there tacks I just don't see? Killer location, but there isn't enough contrast between the rock shelf you're on and the valley floor - too much saturation perhaps.
